May I ask some questions here.
When I tell people that I have a job at some place, should I say...
"I work at a restaurant." or "I work in a restaurant."?
Does it depends on the article I use? If it is "a", that means I don't specify the place, so I say "in a restaurant". But if I tell people the name of the restaurant I work for, I must say "I work at ABC restaurant." Is it correct.?
What about the following sentences. Please correct them for me. Thanks.
I work at the airport.
I work in an airport.
I work at the bookstore.
I work in a bookstore.
